Find the angles in the image
Rama09 [41]

Answer:

  • a) 36°, b) 36°, c) 72°

Step-by-step explanation:

<h3>Given:</h3>
  • PT║VW and SR is transversal
  • m∠PQR = 36°
<h3>To find:</h3>
  • a) m∠SQT
  • b) m∠QRW
  • c) m∠PRV
<h3>Solution</h3>

a) ∠SQT is vertical with ∠PQR and therefore has equal measure

  • m∠SQT = 36°

b) ∠QRW is corresponding angle with ∠SQT and therefore has equal measure

  • m∠QRW = 36°

c) m∠PRV = m∠PRQ as marked equal

  • m∠PRV +m∠PRQ + m∠QRW = 180° as straight angle
  • m∠PRV*2 = 180° - 36°
  • m∠PRV*2 =144°
  • m∠PRV = 144°/2
  • m∠PRV = 72°

Find Y if AB bisects DAC and CB bisects ACE
xxMikexx [17]

Answer:

L1 and L2 are parallel

BAC = 58° as it is given in the question that AB bisects DAC

similarly BCE = y°

angle B = 90° ( from figure)

Y + 58° + 90° = 180 ( angle Sum property of a triangle).

Y + 148° = 180°

Y = 180 - 148

Y = 32°
